Samsung Galaxy J1 (SM-J100MU) Firmware Overview
What is the latest SM-J100MU firmware?
J100MUUBU0AQC1, released September 20, 2017 with Android 4.4.4. It is a feature update on bootloader binary 0. The archive holds 20 official builds across 16 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung Galaxy J1 still getting updates?
Most likely not: there has been no new firmware since September 2017, so Android 4.4.4 is the last version this model got. The final builds below are still the best choice for a clean reinstall.
Can I downgrade the SM-J100MU firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 0:
- Binary 0 — since Feb 2015
